    • Experimental investigation into radar-based central blood pressure estimation 

      Solberg, Lars Erik; Aardal, Øyvind; Berger, Tor; Balasingham, Ilangko; Fosse, Erik; Hamran, Svein-Erik (2015)
      To assess whether radar technology can be used for monitoring blood pressure via information from the aorta, two experiments were performed: (i) measurements on a phantom model and (ii) acquisitions on a human subject for ...

    • In-Body to On-Body Ultrawideband Propagation Model Derived from Measurements in Living Animals 

      Floor, Pål Anders; Chavez-Santiago, Raul; Brovoll, Sverre; Aardal, Øyvind; Bergsland, Jacob; Grymyr, Ole-Johannes; Halvorsen, Per Steinar; Palomar, Rafael; Plettemeier, Dirk; Hamran, Svein-Erik; Ramstad, Tor Audun; Balasingham, Ilangko (2015)
      Ultra wideband (UWB) radio technology for wireless implants has gained significant attention. UWB enables the fabrication of faster and smaller transceivers with ultra low power consumption, which may be integrated into ...

    • Medical radar literature overview 

      Aardal, Øyvind; Hammerstad, Jan (2010)
      Dette dokumentet presenterer en oversikt over litteraturen innen feltet medisinsk radar, med hovedfokus p˚a hjerteslag- og pustdeteksjon, ultrabredb˚ands (UWB) medisinsk radar og avbildning i medisinsk radar. Først blir ...

    • Physical Working Principles of Medical Radar 

      Aardal, Øyvind; Paichard, Yoann; Brovoll, Sverre; Berger, Tor; Lande, Tor Sverre; Hamran, Svein-Erik (2013)
      There has been research interest in using radar for contactless measurements of the human heartbeat for several years. While many systems have been demonstrated, not much attention have been given to the actual physical ...

    • Radar sensitivity to human heartbeats and respiration 

      Aardal, Øyvind; Brovoll, Sverre; Paichard, Yoann; Berger, Tor; Lande, Tor Sverre; Hamran, Svein-Erik (2015)
      Human heartbeats and respiration can be detected from a distance using radar. This can be used for medical applications and human being detection. It is useful to have a system independent measure of how detectable the ...

    • Time-lapse imaging of human heart motion with switched array UWB radar 

      Brovoll, Sverre; Berger, Tor; Paichard, Yoann; Aardal, Øyvind; Lande, Tor Sverre; Hamran, Svein-Erik (2014)
      Radar systems for detection of human heartbeats have mostly been single-channel systems with limited spatial resolution. In this paper, a radar system for ultra-wideband (UWB) imaging of the human heart is presented. To ...
